Default h23a1 forged rod piston combo?

just wondering what setup you guys are using, price, and where you guys got it from. not a lot of h23a1 aftermarket support. I think I've asked 3 sponsors on here and they had to use h22a rods with custom pistons. a little bit too pricey for me. got a h23a1 block for pretty cheap so I'd prefer to go h23/VTEC turbo.

I used the Import Builders H23 rods in my build which is now called blueprintmfg.com If it were for turbo I'd go with the Crowers or Pauter. The I just used an H22 Wiseco piston.

Using H22 rods with custom pistons isnt as pricey as you may think. Its usually about $150 more for custom pistons. I had some quoted the other day for $550 which I didnt think was bad at all, wait time was gonna be 2 months though.

more than you could likely power the h23 to for the streets

hmmn me neither, shoot Jeff a PM and find out, I bet he still has some. He's the guy to talk to about custom pistons as well if you go that route. Heres the thread...

https://honda-tech.com/zerothread?id=2179750

Nobody makes an off the shelf H23 piston, even if they advertise it as so watch the comporession height because it is most likely an H22 piston. The only difference is the .02" taller compression height of the H22 piston meaning that in would stick out of the block that far with an H23 rod/crank setup.

So in other words I need custom rods and pistons? I think Crower makes rods for the H23, but at a price of 700+...

no either H23 rods and H22 pistons and let them stick out of the block .02" (what I did)

OR

off the shelf H22 rods and custom pistons with a shorter compression height to compensate.

Sorry I ask so much, so there is no disadvantage to running h22 rods and pistons that will stick out that extra .02"?

Default Re: h23a1 forged rod piston combo?

Sorry I know this thread is way old but this thread is the closest I've seen come to solving my issue. I too have an h23a1 engine and can't find rods anywhere unless I pay 700+, However h22 rods will work but if I get the pistons too it will throw the compression ratio off. I'm going for a 9:1 C/R and the only thing I can think of is to go with Eagle H beam h22 rods and get custom forged pistons. This seems to be the most simple way of doing things but I don't really know how to measure everything out for the custom pistons I need to make. Anyone know how this is done?

JE makes forged pistons specifically for the h23

yes I see that but how will it work with the rods? If I put h22 rods in there won't it throw the c/r off? I've heard of people keeping the stock rods but I'm a very nervous about that, my goal is 300Whp on prolly 9psi...might push more to see what i can get out of it but I want the motor to hold up way more than it will be pushing.

oh and thanks for replying, I've been on 2 different forums and posted on 5 or 6 different threads about this....the prelude or h22 and h23 seems to be a dead subject.

If you want peace of mind I would use forged rods since you are going to the extent of sleeving the block and running forged pistons. I am running a turbo H23 making 300whp using these connecting rods:

http://www.crower.com/products/conne...-2-2-5473.html

and these pistons:

http://www.jepistons.com/Catalogs/Sp...ura/h23a1.aspx

Is your concern price and that is why you are trying to see if h22 components will work in your h23 bottom end?

Price is certainly not a concern, I've only been finding everything h22. So that is why I asked. My goal is what you have, 300Whp. I will definitely take a look at those rods and pistons. How long have you been running boost on those internals?

Edit: just looked at those links. The crower rods I have seen but on a different site, they listed them as h22 and I couldn't find h23 but this is good. The pistons I knew were there but didn't know if the h22 rods and h23 pistons would work. Excellent, I will go with this combination, my other question is I ordered Darton Flanged sleeves for an h23 which were made for an 87mm bore. Now the pistons I'm getting are 87.5, I should be fine to bore the sleeves out another .5 right?

I have been running these internals for about 5 years now. When I bought my JE pistons they had an option for a 88mm piston and that is what I went with. I also have darton flanged sleeves so I would imagine boring to 87.5 shouldn't be a problem. Maybe check with darton to make sure.

Wow, 5 years is pretty solid. I emailed Darton to find out if I can bore those sleeves out .5mm. Thank you so much for all the help. I will definitely be in contact w/ you considering you have the same build I'm going for. But until then thank you again.
